# DeviseSessionLimit

Devise plugin preventing a user from having multiple open sessions

Using code from [https://github.com/phatworx/devise_security_extension](devise_security_extension)

## Installation

Add this line to your application's Gemfile:

    gem 'devise_session_limit'

And then execute:

    $ bundle

Or install it yourself as:

    $ gem install devise_session_limit

## Usage

In your `User` model:

    class User

      # Additional field

      field :unique_session_id, :type => String

      # Additional devise module

      devise ..., :session_limit

    end

Add some translation key for the error message:

    en:

      devise:

        failure:

          session_limited: "You are already signed in from another place"

## Customize

You can customize the behaviour from the `User` model by overriding or chaining this two methods:

      # Called at each sign in

      def update_unique_session_id!(unique_session_id)

        self.unique_session_id = unique_session_id

        save(:validate => false)

      end

      # Called at each request, you can override to implement your own behaviour

      def check_unique_session_id session_id

        self.unique_session_id == session_id

      end
